Been working this week on setting up the 2011 Miata 6 speed as a toad for the B+. The Roadmaster baseplate & adapter bar is on, wiring all done but brake and tail lights. Left to do is disable steering lock and change transmission lube to Ford MoCo full synthetic. "Healyman's" website is a very good source as are the various Madza Miata racing sites on towing and racing requirements (no steering lock). Yes it is "not tow-able" per Mazda but can be and is, with several modifications. Won't be able to try set up until July. Will be at the FMCA rally in Goshen this week, then going to SD via MS (reunion) for driver's license renewal.
BTW the "three hour" job is now at about 20.
